Well by the time we picked Kiwi up from the boarders on Tuesday she looked perfect. This morning, she had plucked again.
Don't know why. I'm not taking her to the vet again (unless she starts chewing her skin and bleeding or whatever) because we already know there's nothing physically wrong with her. But we really don't know why she'd pluck again. It's not like she can be distracted to not do it, because she only does it overnight when she's settled down to sleep and not during the day.
So it's a mystery.
